Description

Technical Field

[0001] The invention relates to the technical field of ventilation equipment, in particular to a building ventilation structure. Background Art

[0002] Building ventilation refers to the direct or purified discharge of dirty indoor air to the outside of a building, and the replenishment of fresh air to keep the indoor air environment in line with hygiene standards. Building ventilation is an important means to ensure indoor air quality and regulate indoor climate. It is mainly divided into two methods: natural ventilation and mechanical ventilation. Its main purpose is to maintain the freshness of indoor air, reduce the accumulation of pollutants, and improve the comfort and health of residents.

[0003] At present, the most basic way of building ventilation is to open windows for ventilation. However, in the actual ventilation process, simple window ventilation cannot meet some of the needs of indoor ventilation in buildings. For example, window ventilation can only rely on natural conditions for ventilation. When there is no wind or the wind is relatively small outside, opening windows cannot reflect the ventilation effect. And if the outdoor environment is more complicated, such as when there is loud noise, dust and sand, opening windows for ventilation will cause the indoor environment to be adversely affected by the outside world. Therefore, we proposed a building ventilation structure to solve the above problems. Summary of the invention

Specific implementation manner

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-13 , the present invention provides a technical solution: a building ventilation structure, including a device main body 1, telescopic seats 2 are connected to both the upper and lower ends of the device main body 1, a clamping seat 15 is fixed to the outer end of the telescopic seat 2, and a clamping component for clamping and connecting the position is provided inside the clamping seat 15.

[0034] Furthermore, the clamping component includes a limiting slide bar 16, a first screw 17 and a limiting block 18. A limiting slide bar 16 and a first screw 17 are provided inside the clamping seat 15. The limiting slide bar 16 is fixedly connected inside the clamping seat 15, the first screw 17 is rotatably connected inside the clamping seat 15, and two limiting blocks 18 are provided on the upper side of the clamping seat 15, and both are penetrated and connected by the limiting slide bar 16 and the first screw 17.

[0035] Even further, the limiting slide bar 16 and the first screw 17 are both hidden inside the clamping seat 15, which can prevent the limiting slide bar 16 and the first screw 17 from contacting the outside, ensure the stable working state of the limiting slide bar 16 and the first screw 17, and the limiting slide bar 16 is slidably connected to the limiting block 18, and the first screw 17 is threadedly connected to the limiting block 18, which can ensure the stable position movement of the limiting block 18.

[0036] Furthermore, first knobs 3 are fixed at both ends of the first screw rod 17, and the first knobs 3 are located outside the clamping seat 15, which is convenient to control the first screw rod 17 through the first knobs 3. The threads on the first screw rod 17 are two-way threads symmetric in the middle. The two limiting blocks 18 form a moving structure with opposite directions on the clamping seat 15 through the first screw rod 17, and the clamping and limiting work can be realized through the two limiting blocks 18.

[0037] A ventilation net plate 7 is installed on the side of the device main body 1 through bolts. A fixing frame 12 is fixed inside the device main body 1, and a fan 13 is installed on the fixing frame 12. The position of the fan 13 is opposite to the position of the ventilation net plate 7.

[0038] A rotating rod 11 is installed in the middle position of the fixing frame 12 through a bearing. Both ends of the rotating rod 11 are in threaded connection with the telescopic seats 2. The rotating rod 11 is in transmission connection with the rotary handle 5 through a bevel gear set 10, and the rotary handle 5 is installed on the outside of the device main body 1 through a bearing.

[0039] Further, the telescopic seats 2 are always sleeved on the inner sides of both ends of the device main body 1 to ensure the stable working state of the telescopic seats 2. And the telescopic seats 2 form a telescopic structure at both ends of the device main body 1 through the rotation of the rotating rod 11, and the combined size of the telescopic seats 2 and the device main body 1 can be adjusted, so as to be suitable for installation work on windows of different sizes.

[0040] A ventilation hood 8 is arranged on the outside of the device main body 1. A wind shield blade 9 that can be turned over and moved is arranged on the ventilation hood 8. Sound insulation cotton is pasted on the inner side surface of the wind shield blade 9, which can play a sound insulation effect after the wind shield blade 9 is closed. An adjusting assembly for controlling the opening and closing angle of the wind shield blade 9 is arranged inside the wind shield blade 9.

[0041] Further, multiple groups of wind shield blades 9 are arranged on the ventilation hood 8 to realize the opening and closing and ventilation of the ventilation hood 8. External connection rods 23 are fixed on the inner sides of both ends of the wind shield blade 9. The external connection rods 23 on the same side of one end of the wind shield blade 9 are movably connected to the same linkage rod 24, so that the opening and closing rotation of one wind shield blade 9 drives all the wind shield blades 9 to move synchronously, ensuring the stable and synchronous working state of the wind shield blades 9.

[0042] Further, the adjusting component includes a connecting rod 20, a second screw rod 21, a threaded sleeve 22 and a gear 14. The threaded sleeve 22 is installed on the device main body 1 through a bearing, enabling the threaded sleeve 22 to rotate on the device main body 1. A second knob 6 is fixed to the outer end of the threaded sleeve 22, and the second knob 6 is located outside the device main body 1, facilitating the operation of rotating the threaded sleeve 22 through the second knob 6. Two threaded sleeves 22 are provided on the device main body 1, and the two threaded sleeves 22 are driven by the gear 14 to ensure synchronous rotation of the two threaded sleeves 22. The second screw rod 21 is threadedly connected to the threaded sleeve 22, and the ends of the two second screw rods 21 are fixedly connected to the connecting rod 20, ensuring that the two second screw rods 21 cannot rotate when connected to the two threaded sleeves 22. Thus, the synchronous rotation of the two threaded sleeves 22 can cause the two second screw rods 21 to drive the connecting rod 20 to move back and forth.

[0043] Furthermore, both ends of the connecting rod 20 are inserted and connected to the connecting collar 19, and the connecting collar 19 is fixed to the inner side of the wind deflector blade 9. The rotation and opening / closing of the wind deflector blade 9 can be driven by the movement of the connecting collar 19. The outer shape of the connecting collar 19 is strip-shaped, and the width of the through opening on its inner side is equal to the outer diameter of the connecting rod 20, ensuring that the connecting rod 20 stably drives the connecting collar 19 to move.

[0044] Further, the bottom of the ventilation hood 8 is in an open shape, and a dust-proof filter screen 25 is fixed inside its open-shaped structure. When the wind deflector blade 9 is completely closed, ventilation can be carried out at the bottom of the ventilation hood 8, and at the same time, the dust-proof filter screen 25 can ensure that the indoor environment is not affected by the external environment.

[0045] Handles 4 are fixed to the side surface of the device main body 1, and one handle 4 is provided above and below the side surface of the device main body 1 respectively, facilitating the holding of the device main body 1, and thus facilitating the disassembly and assembly of the building ventilation structure.

[0046] Working principle of this embodiment: When using this building ventilation structure, first install this building ventilation structure into the frame of the sliding window. If the sliding window has two sashes, this building ventilation structure can be installed against the side window frame, which will not affect the opening and closing of the two sashes. If the sliding window has multiple sashes, this building ventilation structure can be installed between the sliding windows, and at the same time, it will not affect the sliding of the windows.

[0047] When installing the building ventilation structure, the installer holds the handle 4 and lifts the building ventilation structure vertically and places it on the window frame. The clamping seat 15 at the lower end of the device body 1 will be in direct contact with the window frame. Then, rotate the rotary handle 5. Through the transmission of the helical gear set 10, the rotating rod 11 inside the device body 1 rotates. The two ends of the rotating rod 11 are threadedly connected to the telescopic seats 2, so that the telescopic seats 2 perform telescopic work inside the two ends of the device body 1, changing the combined length of the telescopic seats 2 and the device body 1, so that the clamping seats 15 at the two ends of the device body 1 are respectively in contact with the upper and lower sides of the window frame;

[0048] After that, rotate the first knob 3 to rotate the first screw rod 17 in the clamping seat 15, and then the position of the limiting block 18 on the clamping seat 15 can be adjusted, so that the limiting block 18 can clamp the window frame, thus completing the positioning and installation work of the building ventilation structure. When the building ventilation structure is installed on the window frame, the opening and closing and pushing and pulling of the window are not affected. The side of the window is in contact with the side of the device body 1, and it can still play the role of closing the window;

[0049] When performing ventilation work, the fan 13 is powered on and starts to blow. At the same time, rotate the second knob 6 to rotate the threaded sleeve 22 on the device body 1. As long as one of the two threaded sleeves 22 on the device body 1 rotates, the other will rotate synchronously under the drive of the gear 14. When the threaded sleeve 22 rotates, the second screw rod 21 threadedly connected to it is connected to the same connecting rod 20, so the second screw rod 21 does not rotate and will drive the connecting rod 20 to move forward;

[0050] As the connecting rod 20 moves forward, the connecting clamping ring 19 connected to it will change its position, so as to control the opening and closing of the windshield blades 9 through the connecting clamping ring 19. The rotation of one windshield blade 9 can make all the windshield blades 9 communicate synchronously through the external rod 23 and the linkage rod 24, so as to control the opening and closing of all the windshield blades 9. At the same time, since the inside of the connecting clamping ring 19 is a long strip through hole and the connecting rod 20 can move inside the connecting clamping ring 19, the forward movement of the connecting rod 20 can normally drive the connecting clamping ring 19 to drive the windshield blades 9 to rotate, and there is no movement interference between them;

[0051] After that, by rotating the second knob 6 to open the windshield blades 9 on the ventilation cover 8, efficient ventilation can be carried out through the fan 13. If the external environmental quality is poor and normal ventilation will have an adverse impact on the indoor environment, the windshield blades 9 can be closed. At the same time, the windshield blades 9 are provided with sound insulation cotton, which can play a sound insulation effect on the indoor after the windshield blades 9 are closed. When the fan 13 is working, the air flow will circulate through the lower opening of the ventilation cover 8 and, under the action of the dust-proof filter screen 25, ensure that the dust outside will not affect the indoor environment;

[0052] When the building ventilation structure is not in use, the rotary handle 5 can be rotated to contract the combined length of the device body 1 and the telescopic base 2, separating the upper clamping seat 15 from the window frame, and then the handle 4 can be held to quickly complete the disassembly of the building ventilation structure;

[0053] The above is the usage process of the building ventilation structure, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
